Interfacial Mo, W-Conjugated Polarization, and Oxygen Vacancies of MoO2/WO3 in Enhanced Microwave Therapy for MRSA-Induced Osteomyelitis

“…The peaks of W 4f, Mo 3d, Mo 3p 1/2 , and Mo 3p 3/2 can be clearly observed. On the basis of the XPS energy spectrum of W 4f in Figure S4b, the combination of MoO 2 with WO 3 makes the W 4f peaks shift to a lower binding energy and increases the charge density around W. [40][41][42]54 As shown in Figure S4c, the peaks of Mo 3d of MoO 2 /WO 3 shifted compared with MoO 2 alone, which suggests electronic interaction after the combination between MoO 2 and WO 3 and an increase in the charge density around Mo and W. 37 The O 1s narrow spectra (Figure 1f the Table S1 showed the percentage content of each peak. In the surface oxygen vacancies region, OH can bond with cations to achieve charge balance; therefore, the content of oxygen vacancies is related to O OH .…”

“…Because of its electrical conductivity, the surface of MoO 2 has a mass of free electrons, thus exhibiting a strong localized surface plasmon resonance effect (LSPR) under irradiation. , The monoclinic WO 3 has similar properties. The existence of oxygen vacancies changes the valence state of W and enhances the carrier concentration, which results in the LSPR effect. , Moreover, the WO 3 and MoO 2 oxygen vacancies and interfacial oxygen vacancies can affect trapping centers for electrons or holes, promote the separation of electrons and holes, induce the interfacial charge, tune the Schottky barrier, reduce the interfacial resistance, facilitate the movement of electrons across boundaries, adsorb and activate gaseous oxygen, − and enhance its localized plasmon resonance effect (LSPR). , Compared with single metal oxides, binary metal oxides have higher conductivity and more abundant oxygen vacancies, which can improve the more active sites for electron migration and dipole polarization because the polarization of the binary metal oxide interface can enhance its conductivity loss, thereby improving the microwave absorption performance of binary metal oxides. , …”

Fabrication of Hierarchical Porous Metal Oxides by the HPMC-Assisted Gel Combustion Strategy: Incorporation of Nanoceria into Cookie-like Mn2O3 with Enhanced Oxidation Activity and Excellent Water Resistance

“…The 5%CeMn-H catalyst in the sample has the highest Mn 2+ content (31.01%), and the Mn 2+ content in Mn 2 O 3 -H and Mn 2 O 3 -B catalysts is 29.73 and 28.31%, respectively. Generally, low valence Mn 2+ shows great potential to appear oxygen vacancy, 54 which is beneficial to the mobility of lattice oxygen. Furthermore, the mixed oxide formed by the addition of Ce would undergo a redox cycle like Mn 3+ + Ce 4+ ↔ Mn 4+ + Ce 3+ , resulting in the increase of high valence Mn 4+ in 5%CeMn-H. With a higher manganese state (Mn 4+ ), more surface adsorbed oxygen species could be generated, 55 further leading to high activities in related oxidation reactions. )…”

Regulating the interfacial charge separation between MoS2QDs and sea-urchin graphitic carbon nitride for deep photodegradation of tetracycline under visible light

“…6 Photodegradation treatment is a pollutionfree, green, and sustainable technique that uses an advanced oxidation reaction to generate reactive oxygen species to decompose target pollutants. [7][8][9][10] As one of the most promising photocatalysts, CN gains popularity in recent years due to its low cost, tunable electronic structure, high physicochemical stability, and environmental friendliness. [11][12][13] However, numerous publications on CN photocatalysis revealed that its photoactivity is limited by poor visible light absorption, rapid recombination of charges, and slow surface kinetics.…”
